SBG Systems Releases Virtual Base Station Feature in Qinertia

SBG Systems is introducing the Virtual Base Station feature in its in-house post-processing software called Qinertia. Geospatial professionals benefit from an optimal centimetric position accuracy in all their projects, even for corridor mapping and in poorly covered RTK areas. Qinertia is SBG Systems’ in-house GNSS and INS post-processing software. It gives access to offline RTK corrections from more than 7,000 base stations located in 164 countries. Trajectory and orientation are then greatly improved by processing inertial data and raw GNSS observables in forward and backward directions. Corridor survey accuracy Qinertia PPK software now includes a brand new Virtual Base Stations... (read more)

Klau Geomatics Releases Mapping Payload for DJI M3000

Klau Geomatics has released a new mapping payload for DJI M3000 that weighs just under 1 kilogram. A KlauPPK module mounted via the Klau Geomatics Sony gimbal connects straight into the DJI bayonet mount, together with an RX12r camera. The payload (gimbal and camera) weighs a little less than 1 kilogram. The payload is independent of the drone; there is no data connection to the drone. Photos are therefore only on the camera, which is stabilized and tilted via remote control. Klau Geomatics says that flying with this payload eliminates the need for ground control points (GCPs), but the company recommends... (read more)

A Commercial Drone Mapping Solution Using the Phantom 4 PPK

Previously, people had to invest more than 30,000 dollars to purchase professional mapping drones and place a large number of control points on the ground to get accurate, survey-grade maps. This situation continued until DJI released the Phantom 4 series of commercial drones with integrated GNSS antenna and high-definition gimbal cameras. This paper proposes a commercial drone mapping solution using the Phantom PPK to significantly reduce control points, and explains the workflow, testing methods and how the results support this level of drone mapping accuracy. (This article is brought to you by Hi-Target and was written by Richard Pan and... (read more)

KlauPPK Usage Leads to Changes in GCP Regulations in Japan

Japan’s Ministry of Land, Infrastructure, Transport and Tourism has rewritten its UAV capture specifications based on results using KlauPPK technology. The guideline for work-type management using aerial photogrammetry (earthwork), which outlines the procedures to be used to perform aerial surveys, has until now specified that surveyors must “set up ground control points every 100m”. When KlauPPK technology is deployed, the use of GCPs is now optional. The tests conducted by GeoLink Japan proved that +/-5cm XYZ accuracy can be achieved without GCPs, as verified with check points. This improves the work efficiency and productivity across sites in Japan including public... (read more)

Smart Surveyors: Developments and Trends from the FIG Working Week 2020

Some of the challenges demanding innovative surveying approaches and technologies are rapid urban growth, smart energy, cleaner mobility, and ‘land rights for all’. Sensing technologies, spatial data processing methods, and related approaches are already available. However, the question is how to use and improve them to become future proof, smart surveyors? Only ten years left to achieve the SDGs for a sustainable future. How can smart surveying contribute? To answer these questions, the papers of the FIG proceedings were analysed by the author-team.In this short article, we present the main trends distilled and the papers we refer to, represent these...

Mapping the Yangtze River

One Local Authority, 400kmĀ², 21,000 Images and One Map
The Zhenjiang Municipal Flood Control Bureau is a short walk from the Yangtze River: staff can clearly see the river from the office. In July 2019, a massive orthophoto was created from 21,000 images, representing 400 square kilometres. Before this, the region's flood planning maps, water conservation data and related information were stored as separate, discrete files. For such a big project, the team needed to bring all these together with a custom base map. Zhenjiang is a transport hub lying on the southern bank of the Yangtze River near the Grand Canal, and at constant risk of floods. The... (read more)
